CHARLES H. TRYON, OF SYRACUSE, NEW YORK.

STOVE--PIPE THIMBLE.

SPECIFICATION forming part of Letters Patent No.374,643, dated December 13, 1887.

Application filed October 16, 1886. Serial No. $216,389.V (No model.) I

To all whom, it 71mg/ concern.-

Be it known that I, GHAELEs H. TIaYoN, of Syracuse, county of Onondaga, in the State of New York, a citizen of the United States, have invented certain new and useful Improvements in Stove-Pipe Thimbles, of which the following is a specification. r

My invention relates to an improvement in 'stove-pipe thimbles and method of manufacturing the same. The objectis to provide a thinible which shall be more durable and convenient than those hitherto manufactured,and which can be furnished at a reduced cost.

Vth these ends in view my invention con-v one of the ends ofthe thimble, and Figs. 4, 5,

6and 7 are views in detail.

A and B represent the ring-shaped ends of the-thimble, each of which is provided with an annular ilange, a, o n its side toward the opposite end. At points a suitable distance apart, preferably at two diametrically opposite points, each of the flanges is re-enforced, as shown at C, forming bossesv for more securely supporting the adjusting hooks D. Ihese hooks D are formed of a good quality of Wire, and are s et in the molds in which the rings A B are cast in positions to occupy the centers of the bosses C. The metal for the ends A and B is then cast into the molds around the ends of the hooks D, and when cool hold them in position as though a part of themselves. One of these ends-B, for example-is provided with a tubular section, F, one end of which.

iits around the outer face of the flange a out'- side-of the hooks D, and the opposite end is adapted to telescope within the open end of a similar tubular section, F, secured to the vend j .A around its iange a. y

To avoid the labor andexpenseof riveting or bolting the tubular sections F to the ends,

I nd it expedient to solder them to the stems .and without any labor of drilling or riveting `the hooks to the ends, and my tubular sections are also secured in a lsimple and economical manner, thus rendering the entire cost of manufacturing much less than heretofore, and at the same time producing a better, or equally as good, product.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-,

1. The herein-described stove-pipe thimble, consisting, essentially, of the cast-metal ringshaped ends having adj usting-hooks cast therein, the tubular telescopic sections or casing soldered to said adj usting-hooks, whereby they are secured to said ends,and the springs engaging the adj usting-hooks, substantially as described.

2. In a stove-pipe thimble, the combination Y ofthe cast-metal ring-shaped ends, the annular flanges a, cast integral with said ring-shaped ends, the wire adj usting-hooks cast in said ringshaped ends, the telescopic sections F, adapted to engage the outer faces of said flanges a and be attached to said ring-shaped ends by beingsoldered to said adj usting-hooksand the springs engaging said hooks, substantial] y as described.

In witness whereof I have hereunto `set my hand this 11th day of October, 1886.

CHARLES H. TRYON.
